The EMOKO C91 is a moped-style fat-tire e-bike with a 1000W motor and a 48V 20Ah (960Wh) battery. Its 20 x 4.0-inch tires, rear rack, disc brakes, Shimano gears, front light and LCD suit a rider who wants a sturdy utility bike rather than a light bicycle.

Top speed is set at 15.5 mph, and range is rated at up to 37 miles. It weighs 70.5 lb.

StreetRides ships the EMOKO C91 to riders in Seattle, New York, San Diego, Miami and across the U.S.

Best for riders with secure ground-level storage who want moped-style proportions, a broad tire footprint, and a rear rack for errands or leisure rides. The seat color changes the look, not the specs.

Think twice if you must lift the bike onto stairs or a rack, since it weighs 70.5 lb, or if you need UL 2849 certification.

The C91 has a 1000W motor, mechanical disc brakes at both wheels, a Shimano seven-speed drivetrain, and 20 x 4.0-inch tires. That combination favors direct controls and a stable, wide-tire feel, but cable brake setup and pad wear deserve regular attention.

Top speed is set at 15.5 mph and cannot be changed. The 1000W motor is above the 750W limit some states use for e-bikes, so check your state and local rules.

The 48V 20Ah lithium-ion battery holds 960Wh. EMOKO rates range at up to 37 miles, and a full charge takes 7 to 8 hours.

Your load, speed, cold, hills, tire pressure and assist level all change range. Plan an overnight charge and keep a reserve.

EMOKO lists front and rear mechanical disc brakes, a front light and an IP54 rating for splashes and light rain.

EMOKO does not list a UL certification for the C91. Check your state and local e-bike rules before riding.

Before the first ride, check fastener torque, brake alignment, tire pressure, wheel security, light operation, and drivetrain adjustment. A local bicycle shop may handle normal tires, chains, gears, and brake wear, but confirm electrical-service willingness before assuming support.

EMOKO covers the frame for 2 years and the battery and parts for 1 year. StreetRides helps you with claims. StreetRides returns: request within 7 days of delivery, 20% restocking fee.

Motor and controls: 1000W motor. Thumb throttle. Shimano 7-speed. LCD showing battery, speed, gear and errors. Top speed 15.5 mph.

Battery: 48V 20Ah (960Wh) lithium-ion. Range up to 37 miles. 7 to 8 hour charge.

Chassis: aluminum frame. Moped-style saddle. 20 x 4.0-inch tires. Front and rear mechanical disc brakes. Front light. Rear rack.

Capacity: 70.5 lb bike weight. 265 lb max load. Rear rack 55 lb (25 kg). Riders 5 ft 3 in to 6 ft 5 in.

Protection and box: IP54. Package 57.5 x 12.6 x 30.7 inches (146 x 32 x 78 cm).

The C91 gives you one large 960Wh battery, a cargo-ready rack, fat tires, Shimano gears and a moped-style look.

Pick the Heybike Saturn for hydraulic brakes and UL 2849 certification, or the CycHunter 2.0 for a lower price and a dual-battery option.

KEY ADVANTAGES

Why This Ride Stands Out

  • EMOKO C91 48V 20Ah fat-tire electric bike A 960Wh battery

    The 48V 20Ah battery is rated for up to 37 miles and charges in 7 to 8 hours.

  • EMOKO C91 electric bike with rear cargo rack Cargo limits you can plan

    EMOKO rates the rack to 55 lb (25 kg) within a 265 lb total load limit for rider and cargo.

  • EMOKO C91 electric bike with front light and disc brakes Wide tires need real space

    The 20 x 4.0-inch tires and 70.5 lb weight make ground-level storage the practical plan.

Compare your options

Three moped-style choices, three different compromises

C91, Saturn and CycHunter 2.0 all suit riders who want a sturdy seated e-bike. They differ in battery options, brakes, weight and price.

Why these products
All three are moped-style e-bikes sold by StreetRides US.
StreetRides takeaway

Choose the C91 for one large 960Wh battery and a cargo rack. Choose the Saturn for hydraulic brakes and UL 2849 certification if its weight works. Choose the CycHunter 2.0 for a lower price or a dual-battery option.
